Be it known that I, JAMES, P. CoueHLiN., a citizen of the United States, residing at Chicagmin the county of Cook and State of Illinois, have invented certain new and useful Improvements in Advertising Devices; and I do declare the. following to be a. full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in `automatic stereopticon advertising devices.

One object of the invention is toimprove and simplify the construction and arrangeo this character thereby increasing the elliciency and reducing the cost of manufacturing the same.

Another object is to provide an advertis ing device of this kind which may be constructed for use .indoors or made on a large scale for outside use.

With the foregoing and other objects in view, the invention consists of certain novel features of'ccnstructon, combination and arparts, as will be more fully described and particularly pointed out in the appendedclaim.

In the accompanying drawings, Figure 1 is a side vieivof an advertising device constructed in accordance with the invention, oneside of the casing being removed; Fig. 2 is an enlarged detail front elevation, partly in section; Fig. 3 is a vertical section on the line 3 3 of Fig. 1; Fig. 4 is a horizontal section on the line 4 4 of Fig. 1.

In the embodiment of the invention I provide a casing 1 which may be of any suitable size and shape and provided with suitable doors and openings whereby access may be had to the operating mechanism arranged therein. Arranged in the casing l is a supporting frame comprising a front plate V2 and a rear plate 3 which are held together in spaced relation by shouldered bolts 4 or other suitable connecting devices. Revolubly mounted in the 'plates 2 and 3 'of the frame is a wheel supporting and operating shaft the forward end of which projects through the'front plate 2 and has fxedly mounted thereon a slide carryingjwheel 6, in the outer portion of which are arranged slide holding .devices of any suitable construction with which are adapted -to be engaged the slides or transparencies 7 which s mounte contain the advertising or other matter to be displayed by the machine. On the shaft adjacent to the inner side of the plate 2 of .the fra ie is a ratchet gear 8 while loosely on the shaft-5 adjacent to said1gear is a be l pivotal y mounted a pawl 10 which is adapted to engage the teeth of the ratchet `gear 8 and to turn the latter together with the shaft 5 and wheel 6 through a predetermined distance. The other arm of the bell crank lever 9 is connected by a pitman Patented oet. is, asiel,

rod 11 to a crank disk or eccentric 12 which is ixedly mounted on a counter shaft 13, suitably mounted between the plates 2 and 3 of the sup orting frame. VVhenthe shaft 13 is turned in the proper direction, the crank disk or eccentric 12 will be operated and the movement thereof imparted to the bell crank lever and the pawl 10 to operate the ratchet gear 8 in the manner described.

Any suitable means may be employed for imparting an intermittent movement to the shaft 13 and the part operated thereby. Said mechanism is here shown and preferably comprises a spur gear pinion 14 fixedly mounted on the shaft 13 and which is adapted to be engaged by a toothed segment l5 iXedly mounted on a shaft 16 which is pivotally mounted between the plates 2 and 3 and has lixed thereon one member of operating and speed decreasing gears 17, mounted von suitable shafts jouriialed between the plates 2 and 3 as shown. The train ,of gears 17 are driven by a pulley 18 connected by a belt 19 to a suitable motor l20 arranged in the casing 1. y y "E Revolubly mounted in any suitable man ner in the upper portion of the supporting frame and in the rear of the slide carrying Wheel 6 is a shutter 21 comprising a disk in one side of which is formed a;notch 22. On the shaft of the shutter o'r otherwise ixedly connected thereto is a sprocket pinion 23 which is connected by a sprocket chain 24 to a sprocket pinion 2501i the shaft 13 of the operating mechanism, whereby motion is imparted to the shutter to turn the same at the proper speed.

0n the bottom of the casing 1 is arranged a pair ohorizont-al longitudinali disposed guide or track bars 26| with whic i are slidably connected the lower ends of an adustable lens supporting frame 27 on the upper end of which and directly in line with the uppermost slides in the Wheel 6 is secured crank lever 9 on one arm of which is Y thrown on to va suitable screen provided to receive the same.

' the neXt slide in an operative position. The

'house or box 3l, which contains the light slides Will be exposed for a certain period K jection of the matter on the slide While the the projecting lens 728:, whereby the matter contained on thev slides is projected and Secured by a suitable bracket 29 arranged on the lrear plate 3 of the supporting frame is 'a condensing lens 30 inthe rear of Which is arranged alam of time and the Wheel then turned to bring movement of the shutter i-s so, timed and regulated that When the slide carrying Wheel is moving to change the position of the slides, the shutter-Will be between the light and the slide thereby cutting oli' the View or prochange is being made.

From the foregoing description taken in connection With the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explanation.

i i i i i i i i 1 i i l Various changes in the form, proportion resorted to Without departing from the prin- Vciple or sacrificing any of the advantages of this invention as defined in cla1m.f

Having thus described my invention, what the appended V.In an advertising device of the character described,a supporting frame, a slide carrying Wheel revoiubly mounted thereon, a pawl and ratchet gear connected with said Wheel, a cam operating disk connected With said pawl andl ratchet mechanism, an intermittent driving mechanism to periodically turn lsaid cam, a train of speed reducing gears operably connected with said intermittent driving mechanism, a motor operably connected to said train of gears, lenses arranged in suitable position to project the matter contained on the slides arranged in said wheel, means whereby light is thrown through said slides and lenses, and a shutter to out off said light When the Wheel is turning to change the position of the slide.

ln testimony whereof l have hereunto set my hand in presence of 'two subscribing Wit- HGSSBS.
